Definitions

  • the present invention relates to installations for treating at least one fluid, of the type comprising at least one mass of particulate material in which the fluid circulates in a main direction.
  • the object of the present invention is to provide an improved fluid treatment installation making it possible, in a simple, inexpensive and effective manner, to channel the fluid flow lines in border areas of the mass of particulate material without disrupting this mass or its placement in a container.
  • the installation comprises, in the vicinity of at least one border zone of the mass of particulate material, at least one deflecting surface extending by extending projecting in the mass. from a wall delimiting the mass, the deflecting surface forming an angle with the main direction to locally deflect the circulation of the fluid in the mass and forming with an horizontal plane an angle ( ⁇ ) greater than the natural slope angle of the particulate material.
  • Another object of the present invention is the use of an installation as above for the separation of at least one constituent of a gas mixture, for example the drying or purification of a gas and / or the separation of at least one constituent of a gaseous mixture, for example the purification of a flow of air to be distilled or the production of oxygen and / or nitrogen from a flow of air.
  • the deflecting surface can be completed by a veil to constitute, as shown at the top right and left in FIG. 1, deflector elements in V, symmetrical or not, contiguous or not.
  • the fluid will have to follow, on the vertical edges of the mass 2, a wavy path as shown on the left side of FIG. 1, thus lengthening its path in an area where we conventionally observe bypass paths of the particulate material, without the deflecting surfaces 4 being opposed to a homogeneous filling of the container 1 by pouring of the particulate material via the upper orifice 5 for loading the container 1.
  • a container 1 is shown in a horizontal arrangement, the mass 2 of particulate material resting on a horizontal bottom 6, placed in the container 1, the particulate material being poured into the latter through loading orifices 5 distributed over the along the upper surface of the container 1.
  • the latter in addition to deflectors 4 (not shown), on the side walls of the container 1, the latter comprises vertical transverse deflectors 40, constituted for example by simple flat irons or rings, arranged at regular intervals along the bottom wall of the container, and the upper loading orifices 5 are provided with distribution hoods 41 in the form of pyramid trunks with contiguous bases.
  • the arrangement according to the invention imposes on the fluid a sinuous path also along the upper and lower ends, avoiding bypass at the level of the gravity loading zones. It will be noted, in FIGS. 1 and 2, the presence of a transverse web 30 at the inter-outlet of the mass 2 to favor, downstream, a local widening of the flow and therefore a local slowing down in the vicinity of the wall.
  • FIG. 3 an alternative embodiment of the horizontal arrangement of FIG. 2 has been shown.
  • the upper deflectors are constituted by pairs of plates 42 converging towards one another, towards the orifices 5, at starting from suspension partitions 6, but leaving a loading slot or opening 7 opposite each orifice 5, thus allowing easy filling of the container, continued until drowning the plates 42 in a high reserve of particulate material, allowing in particular a resumption of any compaction of the material in the active part of the container.
  • the plates 42 form, as previously, an angle ⁇ relative to the horizontal greater than the natural slope angle of the particulate material used, conventionally between 20 and 30 degrees.
  • FIG. 4 shows a vertical container 1 containing at least one annular mass 2 of particulate material retained between two concentric perforated walls 8 and 9 delimiting, in container 1, interior 10 and exterior 11 chambers between which the fluid circulates by radial passage of the mass 2.
  • the container in addition to the vertical deflectors 42, here annular, on the bottom, here curved, supporting the mass 2, the container comprises, as shown on the left side of FIG. 4, annular deflectors 43 extending towards each other from the junction zones between the grids 8, 9, and the suspension ferrules of the latter 80, 90, respectively and having, as in the embodiment of FIG.
  • a vertical V-shaped section providing, at their apex, an annular passage 7 located substantially perpendicular to the loading orifices 5 and allowing, via these, to charge the space between the grids 8 and 9 of particulate material, the loading taking place, also here, until the flooding plates 81 and 91 are largely submerged, as shown on the face.
  • the deflecting surfaces 43 constrain the flow of fluid at the upper end of the grids 8 and 9 to pass almost directly from space 10 to space 11, or vice versa, without getting lost in the reserve of particulate material between the ferrules 80 and 90.
